How to change my avatar?
At one stage I was assigned by Codidact an avatar grabbed from Stack Exchange [SE]. Subsequently I have been assigned a different avatar. I'd prefer to revert to the SE version throughout Codidact.
I went to my profile (by clicking my avatar) and then clicked on Edit (https://meta.codidact.com/users/edit/profile) and Browse… . I selected a 17K JPG file with JPG extension and 'Open'ed it. The file name appeared just to the right of the Browse… button. When I then clicked on Save a banner appeared:
Couldn't update your profile.
and under Edit Profile:
There were some errors while saving your profile: • Avatar must be a valid image
I tried again with a slightly larger (75K) bitmap image file with bmp extension and received the same banner and error message.
